Abstract (en)
[origin: WO2011147537A1] The invention relates to a planetary-gear automatic transmission (1), in particular a planetary-gear automatic transmission having at least eight forward gear steps, wherein shifting devices formed by clutches (5) and/or brakes (6) are provided for selecting the individual gear steps and shifting actuators (10, 11) that produce associated actuating forces are provided for actuating the shifting devices (5, 6). The planetary-gear automatic transmission is structured in such a way that all shifting actuators can be and are arranged directly on or directly in the area of the associated shifting devices.
